I develop my application.
The (Database )application is stored In NT.
the program is running on the win 9X.

I want to write a log to check . How many current user to login my system?!
The same user can run the application twice on his own PC.

1.) I can save the datetime/login user as the user login my application.
2.) I also can save the leave time as the user press 'Exit' to logout the system.

Now my problem is, somtimes the Win9X is 'hang' , so the user need to 'end task' the application. or the user may suddenly shutdown/re-boot the computer..while the application is running ..

How can check this event ? Or .. How can check that if the connection is broken ??

Thanks
